Script to create subfolders

I need to create a script that I can run on a file share that will create a specific subfolder in the same location for all folders. vbscript...batch...powershell all are good

Currently the share is setup like below

h:\
h:\year folder (folders are 1965, 1966,1967... up to 2013
h:\year\Building(building folders are named with last 2 year digits then 3 digits sequentially...65001,65002,97001,97135, 12001,12005 and so on).
We have literally thousands of building folders, I need to be able to create a folder called DST off the root of all building folders
